I'm setting up my DNS to go through my employers DNS server and have entered the addresses they provided. They say it's a dynamic DNSSEC provider. I kind of understand this. But I noticed that under the search domains section to the right, there is an entry. What does the search domain for DNS do exactly? I would think my query, would go to the name-server I specified, and they would return the IP. How does this work exactly?
